[jboss-user] [EJB 3.0 Users] - Re: 5.1 - @PersistenceUnit fails to resolve in Servlet when

[jaikiran]

As per the EJB3 Persistence spec section 6.2.2, the persistence unit if packaged in a ejb .jar is visible only within that jar (unless you use the jarname#unitname convention while injecting the persistence context). However if you package the persistence.xml in the META-INF folder of the .ear then it will be visible to all components in the ear.

Having said that i don't know why the presence/absence of EJBs in the persistence jar should show a different behaviour (probably the deployment order of the component changes when the EJBs are added?).
